Which statement describes the general trends in atomic radius and first ionization energy as the elements in Period 3 are considered in order from Na to Cl? (1) Atomic radius increases, and first ionization energy decreases.

(2) Atomic radius decreases, and first ionization energy increases.

(3) Atomic radius and first ionization energy both increase.

(4) Atomic radius and first ionization energy both decrease.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

a electronegativity decreases beacuse the size of nucleus is bigger.

catya your not at all which answer i've seen you do this on another question!
